Detailed Description

A packer planning the best packaging.

Retrieves the solution of packaging by combination permuation and factorial case.

Warning

Be careful about number of products and wrappers.

The time complexity of Packer overs O(m^n). Elapsed time of calculation increases enourmously. Do not use Packer if the digits of number of products or wrappers overs 2.

Constructor & Destructor Documentation

samchon::example::packer::Packer::Packer ( )

inline

Default Constructor.

Definition at line 55 of file Packer.hpp.

samchon::example::packer::Packer::Packer ( shared_ptr< ProductArray > productArray )

inline

Construct from products and wrapper.

Parameters

productArray	Product(s) to input some Wrapper
wrapperArray	Type of Wrapper(s) to be used

Definition at line 67 of file Packer.hpp.

samchon::example::packer::Packer::Packer ( const Packer & packer )

inline

Copy Constructor.

Copy constructor of Packer does not copy children items.

Only copies member variables(productArray, wrapperArray) of Packer's.

Definition at line 80 of file Packer.hpp.

Here is the caller graph for this function:

virtual auto samchon::example::packer::Packer::TAG ( ) const -> string

inlineoverridevirtual

A tag name when represented by XML.

Returns: A tag name

Implements samchon::protocol::Entity.

Definition at line 183 of file Packer.hpp.

virtual auto samchon::example::packer::Packer::CHILD_TAG ( ) const -> string

inlineoverridevirtual

A tag name of children.

< TAG>
<CHILD_TAG />
<CHILD_TAG />
</TAG>

Implements samchon::protocol::IEntityGroup.

Definition at line 187 of file Packer.hpp.

virtual auto samchon::example::packer::Packer::toXML ( ) const -> shared_ptr<XML>

inlineoverridevirtual

Get an XML object represents the EntityGroup.

Archives the EntityGroup's own member variables only to the returned XML object.

Do not consider about archiving children Entity objects' data in EntityGroup::toXML(). Those children Entity objects will converted to XML object by their own toXML() method. The insertion of XML objects representing children are done by abstract method of EntityGroup::toXML().

Archives only data of EntityGroup's own.

[Inherited]: Get an XML object represents the Entity.

Returns an XML object that can represents the Entity containing member variables into properties.

A member variable (not object, but atomic value like number, string or date) is categorized as a property within the framework of entity side. Thus, when overriding a toXML() method and archiving member variables to an XML object to return, puts each variable to be a property belongs to only an XML object.

Don't archive the member variable of atomic value to XML::value causing enormouse creation of XML objects to number of member variables. An Entity must be represented by only an XML instance (tag).
